Could not find SteamVR in input section after build

[kadogo]

Hello,

My system is Debian Buster I wanted to use SteamVR as input so I first tried to follow the wiki (https://github.com/opentrack/opentrack/wiki/Building-on-linux). The build went without any issue but when I start opentracker I don't see "SteamVR".

I think it's just not build, I add the cmake command output in case it can help. I not see "steamvr" in the module section so I guess it's not found by cmake but I don't know why.

$ cmake .

Have a good day. Cheers

I went a bit further.

• I added otr_module(tracker-steamvr) at first line in ./tracker-steamvr/CMakeLists.txt

• I copy the openvr.h files to the tracker-steamvr directory because I didn't know how add a library path

cp /usr/include/openvr/openvr* ./tracker-steamvr/

• I ran the same command as before

cmake .
make
make install

But when I launch ./install/bin/opentrack I have the next error

DEBUG [/home/user/GITS/opentrack/api/plugin-support.hpp:107]: library "steamvr" failed: "Cannot load library /home/user/GITS/opentrack/install/bin/../libexec/opentrack//opentrack-tracker-steamvr.so: (/home/user/GITS/opentrack/install/bin/../libexec/opentrack//opentrack-tracker-steamvr.so: undefined symbol: VR_GetInitToken)"

[kadogo]

I do another message because it stay clearer than edit. By changing the CMakeList I have fixed the Issue and I just need to launch SteamVR first like it's said on https://github.com/opentrack/opentrack/issues/1118

I guess the main issue is that the openvr lib in not properly find but I'm not good enough to know how to fix that properly so I will just add what I did. Don"t hesitate to ping me to make more test if needed.

The evdev protocol is making something weird (the yaw when I look at left/right is making my mouse move up / down instead of left / right). But I will try to build proto-vjoystick that is not build something for something similar than tracker-steamvr.

EDIT: It look vjoystick is only for Windows (based on the WIN32 in CMakeList) so maybe there is a real issue with evdev?

[sthalik]

So it looks like the build system doesn't support system openvr. What happens if you use out-of-tree steamvr as on Windows? The Valve repo has binary releases and that's what I compile-tested on Linux.

[kadogo]

Hello @sthalik

To be honest I didn't do much compilation an my english is not my first language so I not really know the terms like "out-of-tree" but if there are commands or links to guide me I can try them.

I will try to find some information about it to try to advance but if you have ressources or precise commands to try don't hesitate to ping me I will answer so fast as I can.

[sthalik]

Clone the repo from https://github.com/ValveSoftware/openvr, it already has binaries. Point out SDK_STEAMVR to that directory.

[kadogo]

Hello

I did the next command in my opentracker directory

$ git clone https://github.com/ValveSoftware/openvr

I think it doesn't find it but maybe I'm point out SDK_VALVE_STEAMVR in a wrong way.

[sthalik]

Use ccmake.

[kadogo]

I didn't know about ccmake thanks. It looks like it's working same if I have an error when it compile the steamvr tracker

cmake .
ccmake .
# Edit SDK_VALVE_STEAMVR with the path of the openvr repo
# configure and generate in ccmake
cmake .
# I saw steamvr in the modules
make

I tested it on the unstable branch and opentrack-2.3.12 tag it's the same issue.

[sthalik]

Replace ResetSeatedZeroPose with ResetZeroPose(vr::TrackingUniverseSeated);.

[kadogo]

I did the replace and launch make again and now I have this error

[toby3d]

Faced similar problems on the commit db54d8eb86b06.

The default build does not include the tracker-steamvr module. Providing the SDK_VALVE_STEAMVR variable to the directory with the downloaded https://github.com/ValveSoftware/openvr repository and trying to build it will cause errors:

Please see whether this patch works with the current openvr version.

[toby3d]

Please see whether this patch works with the current openvr version.

Okay, now the build is successful and the corresponding menu item is now present in Data Input list. But when I try to start the server the following error occurs:

[sthalik]

@toby3d Can you confirm that openvr works in other apps?

[toby3d]

Can you confirm that openvr works in other apps?

I'm not sure, I haven't used SteamVR before. How can I check?

UPD: After installing the openhmd package, the server startup error changed:
